“Smoldering Intensity”! That’s the keyword. Tennis great Roger Federer sent a tweet to Dwayne Johnson showing off his own version of smoldering intensity:

Hey @TheRock, am I doing the "Smoldering Intensity" right? 🤔 pic.twitter.com/5A5ILEXYNK

When the GOAT tweets you, you respond. And The Rock did with an explanation of the term, which comes from his latest movie, Jumanji.

When you’re the GOAT there is no wrong brother. Perfect form 😉👏🏾👊🏾

for those who don’t know.. “Smoldering Intensity” is one of my character’s strengths in #Jumanji. And like Roger, “Dr. Smolder Bravestone” has no weaknesses

We should see some more smoldering intensity from Federer on Tuesday in Melbourne when he starts his quest for Grand Slam No. 20 at the Australian Open.
